Abstract: Ovalbumin (OVA) was used to improve the gel strength of minced meat products added with soybean protein isolate (SPI). The effect of OVA-SPI mixtures at different ratios on the physicochemical properties and microstructure of minced meat gels was examined. The results showed that OVA-SPI mixtures significantly improved the hardness, springiness, cooking loss, and water-holding capacity (WHC) of sausages (P < 0.05). The smallest fat aggregates were formed in the product added with their 1:1 mixture, which had improved hardness as well as the highest and stable springiness. Besides, it had the best consumer acceptance.

Key words: ovalbumin; soybean protein isolate; meat products; physicochemical properties; microstructure
